The multiple sclerosis D-lemma
February 16, 2013 -- Brant Cebulla
One of the most anchoring arguments from vitamin D proponents calling for higher vitamin D supplementation for both the treatment of some diseases and for general recommended daily allowance is, “It’s safe. It may help, it may not, but it’s safe.” Opponents claim that we need more research, we need to understand exactly how safe and effective it is, before we increase recommendations.

These arguments escalate when we consider some of the diseases vitamin D may be implicated in; diseases like breast cancer, prostate cancer, diabetes and more. It has left patients and health care professionals asking, “So do we supplement, or not?”

In the use of vitamin D in medicine, there is probably no greater dilemma and debate currently than the tussle of whether or not to supplement patients with multiple sclerosis (MS). Research, while evident that vitamin D is essential to some, is just okay to others.

Some of the best evidence supporting a role of vitamin D preventing MS is a pair of cohort-type studies that looked at large groups of people, how much vitamin D they were getting, and whether or not they developed MS. In the Nurses’ Health Study II, a cohort of over 95,000 women, those who took over 400 IU of vitamin D/day had a 40% reduced risk of developing MS than those who did not. In a prospective nested case-control study among 7 million US military personnel, there was a 41% decreased risk of developing MS for every 20 ng/ml increase in vitamin D levels.

This past December, a randomized controlled trial published in the journal Acta neurologica belgica found that vitamin D may prevent or delay onset of MS in those with clinically isolated syndrome (CIS). CIS describes a patient with their first possible manifestation of MS, in which they have some type of neurologic symptom that hints MS may be on the way.

What is vitamin D? While the question would seem to call for a simple answer, the query hasn’t always prompted as straight forward a response as one might expect. Researchers often squabble over whether to classify vitamin D as a “vitamin,” a “hormone,” a “pro-hormone,” a “pre-hormone,” an essential “nutrient” and more. This might lead you to ask, then why do we call vitamin D, vitamin D? Continue reading →  (membership required)
